Will a bad PCV be detectable at the sniffer?
Just curious, if you have a PCV that is stuck closed, will there be any affect on the AFRs? What about if the valve cover ventilation is not hooked up to the intake? Will that affect the AFRs?
I know a car should be in tip top shape for a tune, but would these things greatly degrade a tune?

The valve cover vent hooked up as stock is for providing fresh air TO the crankcase. I can't see where either one should affect AF ratio a measurable amount, but if the valve is stuck closed you'll just be pushing it all out through the valve cover vent. The question remains, why not replace the pcv valve?
